When ordering, please specify packaging code: Typical Circuit CST7030-150LC 4 1 Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with Pri Sec I I leader and trailer ( 25 charge). R V in out T out (1 turn) (N turns) B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply 3 2 + change the last letter of your part number from B to C. D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per Core material Ferrite full reel). Terminations RoHS compliant tin-silver-copper over tin over nickel over 2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, copper 0 Adc. Weight 0.16 g 3. For specific questions regarding frequency range, please contact us at Ambient temperature 40C to +125C cst coilcraft.com. Maximum part temperature +165C (ambient + temp rise) 4. Volt-time product is for the secondary, between pin 1 and 2. Storage temperature Component: 40C to +125C. 5. Primary current of 20 A causes less than 25C temperature rise from Tape and reel packaging: 40C to +80C 25C ambient. Higher current causes a greater temperature rise (see Resistance to soldering heat Max three 40 second reflows at Temperature Rise vs Current curve). +260C, parts cooled to room temperature between cycles 6. Terminating resistance (RT) value is based on 1 Volt output with 20 Amps Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / flowing through the primary. Varying terminating resistance increases or 85% relative humidity) decreases output Voltage/Ampere according to the following equation: RT = Vout Nsec / Iin. Packaging 600/7 reel 2500/13 reel Plastic tape: 16 mm wide, 7. Electrical specifications at 25C. 0.35 mm thick, 8 mm pocket spacing, 3.0 mm pocket depth Refer to Doc 362 Soldering Surface Mount Components before soldering. PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787 PCB Washing.pdf. Specifications subject to change without notice.
